Buying bikes and parts

Consumables are easy and local. Anything specific means ordering online and waiting. Knowing which is which saves weeks off the bike.

There are bike shops here, and for the things that go wrong most often they cover you. The frustration starts when you need one particular component.

The practical approach is to split your buying into two routes and use each for what it is good at.

What local shops are good for

Everyday parts and repairs, which is most of what a bike actually needs.

If you puncture, snap a cable or wear out a chain, you can usually be riding again the same day, though it may take trying a couple of shops. That covers the large majority of failures – which is worth remembering before assuming you must import everything.

What is harder to find

The awkward case is a part that is specific to your bike. A generic chain is easy; a derailleur hanger for one frame model is not. If your bike has anything unusual about it, buy that spare while the bike is working, not after it breaks.

Ordering online

For the harder items, ordering from abroad – most commonly from Chinese sellers – is the route most riders here end up using. It works, and it is often much cheaper, but it comes with conditions.

Making online orders work

1

Measure and check before ordering

Confirm the exact standard your bike uses – speeds, axle type, thread, size. A part that is nearly right is a part you cannot use.

2

Read the specification, not the photograph

Listing images are frequently generic. The written specification is what you are buying.

3

Order early

Anything you will need in a month should be ordered now. Waiting until a part fails means weeks off the bike.

4

Buy consumables in pairs

If you are ordering brake pads or a chain, order two. The shipping wait is the expensive part, not the item.

5

Expect variation in quality

Unbranded parts range from excellent to poor. For anything safety-critical – brakes, steering, forks – buy known brands.

Do not economise on brakes, forks or anything structural. A cheap chain that fails is an inconvenience. A cheap brake component that fails on a descent is not. This is the one place where the local shop having a known brand in stock beats saving money online.

The spares worth having at home

A small box of parts turns most mechanical failures into a twenty-minute job instead of a three-week wait.

Buying a bike

Local shops cover the everyday end well. For anything more specific the choice is between what is available here and importing, which brings shipping and customs into the picture.

Whatever you buy, the checks are the same everywhere – frame, wheels, drivetrain, brakes and fit. The buying guide has the full twelve-point checklist for a used bike, and it covers getting the frame size right, which matters more than any component on it.

The short version

Three rules for buying parts here

Local for consumables

Tubes, tyres, cables, chains and pads are all available locally and quickly. That covers most of what actually goes wrong.

Order specifics early

Anything unusual means weeks of waiting. Buy the spare while the bike still works, not after it breaks.

Never economise on brakes

Cheap consumables are a fair trade. Cheap brake or steering components are not.

Parts questions

Questions about buying parts here

Usually, especially for components. Set against that: weeks of waiting, no practical returns, and more variation in quality. For consumables the local shop often wins once you count the wait.

A derailleur hanger for your frame, if it has a replaceable one. They bend easily, they are frame-specific, and without one the bike is unrideable.

Variable. Fine for many things, and not worth the risk for brakes, forks, stems or handlebars. Buy known brands for anything that would hurt you if it failed.

Common systems, generally yes. Newer or higher-end groupsets are harder, and you may need to supply the parts yourself.

Long enough that you should order before you need it. Treat anything ordered abroad as arriving in weeks rather than days, and plan around that.

If you already own a bike you like, bring it and bring its specific spares. If you are starting out, buying locally is simpler and the shop can set it up for you.
